The pool at the YMCA in south Springfield reopened Saturday after passing tests performed by the Springfield-Greene County Health Department.

The pool closed early last week after the Pat Jones YMCA learned from the department that an individual who used the pool tested positive for the parasite cryptosporidium, which causes the diarrheal disease cryptosporidiosis.

In announcing the closure, the facility — which is located at 1901 E. Republic Road — said the pool was "hyper chlorinated out of an abundance of caution," and that the health department would conduct tests once chlorine levels returned to normal.

Wellness activities, swim lessons and aquatics programming resumed as scheduled as of 6 a.m. Saturday, the facility said on Facebook.
